Firstly, every available realm should be visible and accessible from the "Manage Realms" default tab. There should not be hidden realms that you can only access by searching for them in the search bar.

Secondly, we should be able to sort realms by alphabetical order (ascending and descending), date of creation (oldest-to-newest and vice versa) and popularity.

Thirdly, we should be able to favourite realms and have them appear at the top of the results. That way we can easily access realms that we post in often and reduce the time we spend searching for our desired realms.

Fourthly, every realm should get unique artwork for their thumbnail instead of an image taken from online. Like the Sonic, Memes, FNF, and FNAF realms for example

And finally, we should be able to view the realms we and other users are following from our profiles, just like communities.

All of these features would greatly improve the realm system and the Game Jolt user experience as a whole
